Scientists at McMaster University in Canada have found through mouse experiments that the incidence of gene mutations in the offspring of mice that are highly airborne is much higher than those of unpolluted mice. Their research was published in the latest issue of Science. Science and Technology Daily reported that Professor Quinn, an expert in ecology at McMaster University, observed the gulls and found that the rate of gene mutations in seagulls that are endangered by air pollution was much higher than that of uncontaminated seagulls. He decided to study air pollution on animals. The influence of future generations. Since seagulls are not easy to control, he switched to mice for experiments. He divided the mice involved in the experiment into three groups. One group was exposed to highly contaminated air in the urban area, one group was also placed in a highly polluted city, but placed in a box with a dust filter, and the other group was placed In rural areas away from highly polluted air. By observing the offspring of these three groups of mice, he found that the ratio of gene mutations was similar in the rats in the dust filter box and in the mice in the country, and that the gene mutations were generated in the descendants of the mice under high air pollution. The ratio is one and a half to two times higher than the two groups. Quinn said that although the experiment was done with mice, humans also appear the same.
